1) Most hospital employees are covered by their hospital (Usually at far better rates) compared to workers in different jobs (Again, I suggest you look at the median individual income by a person who is making 35,977 which limits the ability to afford healthcare). Also, just avoid the blatant difference: you are a physician and likely know many other physicians who alone can help you in healthcare decisions. (Something many individuals do not simply have)
2) Apologies, I was speaking about a different savings account. I retract that statement.
3) First, actually read the statement by the pew research. The household income median (2 individuals ) is 65k. That would mean 1 individual would have to make 130k (Double 2-individuals combined, so 1 person = 4 people in terms of income) fall within that range. Physicians fall more than 3.5x that (The annual median household). This is again a massive issue. Someone presents statistical evidence that an individual may have more than 2x a household income(2 people combined) and where they fall in the spectrum. Their argument is, "Nah, I can't take that seriously"—what an amazing rebuttal to that argument. I'll make sure to take it back to the economists in the study.
Furthermore, what does fall within the upper class for you? Again, the average income for a family physician (Lowest specialty) is around 234 thousand dollars, 3.6x the median household income (2 individuals combined). The physician falls within the 96-97 percentile in the entire nation. Where do you think a physician would fall to the average person in the US?
4) The United States healthcare is the highest globally due to astronomical pharmaceutical prices, inflated hospital costs, and, yes, higher physician salaries. Although physician salaries are not the main problem, they are indeed an issue. Quite simply, it's not about "deserving." It's about quality healthcare and the massive issues this nation has due to failure in cost control. I can get into it and speak statistically and empirically about our healthcare system's massive issues, but that would be different conservation altogether. The main issue I am speaking about is where physicians lie in income and how they are incredibly high in the US, as demonstrated by the stats I posted above. Which if somehow you were born into two physicians in the US, it would put you in the highest echelon of the US, putting you at massive advantages and seen as rich by most Americans. (Which is a subjective term and varies from person to person, which is why I put stats and definitions of the upper class) I hope that helped clear things up a bit.
Cheers
